Chapter 12, Problem 1NT

To determine

To explain:

The construction of perpendicular on the line $l$ through the point $P$.

Answer to Problem 1NT

Solution:

Explanation of Solution

Given:

A line $l$ is given and a point $P$ on the line is given.

Approach:

B using the technique as: make $P$ the midpoint of any segment on the line. Now $P$ is equidistant from both the ends and then drawing a point which is equidistant from both the ends and then making a line through both the points will give perpendicular bisector.

The construction of the perpendicular is given in the following figure:
